—— Investigation and reflection on the development of circular economy in Zhaoyuan City

office of zhaoyuan municipal people's government

Zhaoyuan City is located in the northwest of Jiaodong Peninsula, with a total area of 1433 square kilometers. It has jurisdiction over 10 town, 4 sub-district offices and 1 provincial development zone with a population of 580,000. China is one of the first county-level cities to open to the outside world. At present, it ranks 59 th in the top 100 counties and cities in China. In recent years, in accordance with the unified arrangements of the state, the province and Yantai City, we have taken the development of circular economy as a concrete action to implement Scientific Outlook on Development, which has promoted comprehensive, coordinated and sustainable economic and social development. In 2004, the city's GDP reached 654.38+0.62 billion yuan, and local fiscal revenue reached 565.438+0 billion yuan, up by 654.38+09% and 36% respectively. Ten thousand yuan GDP consumes 0.83 tons of standard coal, and takes 36 tons of water, down by 0.28% and 3.2% respectively. The reuse rate of industrial water reached 78.9%, an increase of 5.4 percentage points.

First, the practical significance of developing circular economy in Zhaoyuan City

Circular economy is the main way to implement the strategy of sustainable development, and it is also an important guarantee for the transformation from traditional economy to sustainable development economy and the implementation of Scientific Outlook on Development. Zhaoyuan pays close attention to circular economy, mainly based on the following four considerations:

First of all, Zhaoyuan is a resource-based city. Zhaoyuan city is rich in mineral resources, and currently has more than 2 million tons of mineral reserves. The territory is rich in gold, silver, copper, granite and other mineral deposits, especially gold and granite. At present, the proven reserves, retained reserves and gold output of gold rank first at the county level (city) in China, and there are three large granite deposits. In 2004, the city's total mining output value accounted for 3 1.4% of the city's total industrial output value. Long-term exploitation makes Zhaoyuan, like most resource-based cities, face the heavy pressure of gradual depletion of resources, low recycling rate and fragile ecological environment; Zhaoyuan is also a city with a relative shortage of resources and energy. There are no resources such as coal and oil in the jurisdiction, and the contradiction between supply and demand of land, water and electricity is prominent, which has become an important factor restricting economic development.

Secondly, Zhaoyuan is an industrial city. Zhaoyuan has many industrial categories and a solid foundation. There are more than 0/.400 industrial enterprises/KLOC-0, mainly distributed in high-consumption and high-emission industries such as gold, auto parts, electronics, chemicals, textiles, food and building materials. There is still great potential for the utilization efficiency of resources and energy. In 2004, the city's industrial enterprises above designated size achieved sales revenue of 38.2 billion yuan, profits and taxes of 4.55 billion yuan, up by 49% and 75% respectively, and the added value of secondary production accounted for 6 1.5% of GDP.

Third, the requirements of Zhaoyuan urban and rural residents for environmental quality are very urgent. Since the Tenth Five-Year Plan, Zhaoyuan's GDP has grown at an average annual rate of 15.4%, and local fiscal revenue has increased at an average annual rate of 3 1.3%. With the sustained and rapid economic growth, the living standards of urban and rural residents have been continuously improved. In 2004, Zhaoyuan disposable income of urban households reached 9622 yuan, the per capita net income of farmers reached 4998 yuan, and the balance of residents' savings deposits reached 7.29 billion yuan. While the material life of urban and rural residents is satisfied, higher requirements are put forward for the quality of production and living environment. In recent years, the suggestions of the People's Congress and the CPPCC account for one sixth of the total.

Fourthly, Zhaoyuan has a good foundation for developing circular economy. Since the 1990s, Zhaoyuan City has comprehensively promoted the activities of creating a national health city and a national environmental protection model city, passed the acceptance review for many times in a row, and started the creation of an eco-city in an all-round way. In 2004, it ranked third in the quantitative assessment of comprehensive improvement of urban environment in Shandong Province. Good environmental protection and ecological environment have laid a solid foundation for developing circular economy.

Based on the above understanding, Zhaoyuan City puts the development of circular economy on the important agenda of economic work, and improves the utilization efficiency of resources and energy by lowering the road of circular economy with low consumption, low emission and high efficiency, gets rid of the excessive dependence of economic growth on resources, promotes the transformation of resource-based cities and the transformation of economic growth mode, and realizes the coordination and unity of economic, social and ecological benefits.

Second, the basic practice of developing circular economy in Zhaoyuan City

In recent years, we have made some achievements in developing circular economy and building a resource-saving society in accordance with the requirements of developing circular economy and based on reality, focusing on the transformation of resource-based cities, the transformation of economic growth mode and the creation of eco-cities. Mainly reflected in the following three aspects:

(A) establish a new concept of resources, and promote the transformation of resource-based cities with circular economy.

In the development and utilization of natural resources, we should fully consider the carrying capacity of natural ecosystems, save natural resources as much as possible, continuously improve utilization efficiency, recycle resources, and form a virtuous circle of rational and orderly development and utilization. In the development of resources, unified planning and orderly development are implemented. In accordance with the principle of controlled and protective development, the overall planning of mineral resources, land and water resources shall be scientifically formulated, and natural resources such as land, mineral resources and water shall be protected and rationally developed and utilized according to law, so as to effectively prevent the attenuation and depletion of resources. In recent years, we have successively formulated and promulgated the overall planning of mineral resources, land use control planning and water resources development and utilization planning in Zhaoyuan City, which has provided a solid guarantee for the orderly, scientific and efficient development and utilization of resources according to law and the protection of the ecological environment. In 2004, we started a new round of revision of the overall land planning on the original basis, rationally planned the urban spatial layout, optimized the allocation of land resources, and reserved more incremental space for economic development. In the link of resource utilization, the resource utilization rate and output benefit will be continuously improved. On the one hand, improve the level of intensive utilization from the source to avoid waste of resources and excessive predatory exploitation. For the exploitation of gold, granite and other mineral resources, a strict market access system is implemented, the qualification threshold of prospecting and mining rights holders is raised, and villages and individuals are prohibited from engaging in exploration and mining. In recent years, the certified rate of geological exploration and mining in the city has remained at100%; For land resources, while strictly examining and approving construction land and controlling new construction land, we should improve the intensity of land investment and use efficiency. In 2003, we promulgated the "Regulations on Land Management in Development Zones", which stipulated that the investment of projects entering the development zones should not be less than 6,543,800 yuan per mu; In terms of water resources, strictly review the industrial water use plan, guide enterprises to add water-saving facilities and sewage purification facilities, levy water resource fees on water that exceeds the planned price, and urge enterprises to save water. Strict management of urban self-provided wells and collection of water resources use fees according to law have effectively protected groundwater resources. In 2004, the water intake of ten thousand yuan output value of key water-using enterprises in the city 10 decreased by 48% year-on-year, saving water and increasing efficiency by 4.86 million yuan. The accumulated investment is 654.38+56 billion yuan, and the water-saving irrigation area is more than 440,000 mu, saving 48 million cubic meters annually. On the other hand, vigorously promote recycling and continuously improve the efficiency of resource utilization. In terms of land recycling, various ways are taken to revitalize the land that is inefficient in the city or idle by township enterprises around the city. * * * Excavate 620 mu of collective construction land and 534 mu of state-owned construction land, and revitalize more than 80 mu of land in the process of clearing the mortgage of bank loan land use rights; In the recycling of water resources, we will actively develop the reuse of reclaimed water. Investing 50 million yuan to build the third phase of sewage treatment project will increase the daily sewage treatment capacity to nearly 50,000 tons, and the treatment rate of urban domestic sewage will reach 1.000%. The treated reclaimed water is used for urban garden irrigation and toilet flushing in new residential areas. In the link of resource protection, rectification should be carried out according to law. Around the protection of mineral resources, "four rectification" activities were carried out: First, the mining order was rectified. In 2002, we put the rectification of mining order into the general pattern of "strike hard" rectification struggle, opened the way with criminal law, and comprehensively applied laws and regulations such as mineral resources law, land law, safety law and environmental protection law to carry out the largest rectification of mining order in history. Clean up and ban 395 illegal mines, choose factories 138, and repatriate 7500 migrant workers in the mining area. In addition, comprehensive rectification activities of granite mining order have been carried out, and illegal quarries 16 have been banned successively. At present, the management of mine resources in our city has entered a benign development track, and in 2003, the site meeting of special rectification of non-coal mines nationwide was held in our city. Second, the land market order was rectified. Regularly carry out the rectification of land market order, comprehensively clean up the demarcated but unused land for industrial projects, resolutely recover the reclaimed land for projects according to law, and effectively improve the intensive degree of industrial land. The third is to rectify the order of urban groundwater use. The "Implementation Plan for Underground Wells in Closed Urban Areas" was formulated and promulgated, and illegal well drilling cases 10 were investigated and dealt with according to law. Fourth, the geological environment has improved. We attach great importance to the negative impact of mineral resources development on the economy and society, adhere to the principle of "harnessing while developing", and comprehensively increase the efforts to harness the geological environment. Organized four large-scale mine geological environment surveys and evaluations, found out the foundation of the city's geological environment, compiled and completed the mine ecological environment protection plan of Zhaoyuan City, and successively designated 3 1 protected areas with a total area of 232 square kilometers. At the same time, the Opinions of Zhaoyuan City on Further Strengthening Geological Environment Management and the Provisions on the Collection of Geological Environment Management Reserve Fund for the Development and Utilization of Mineral Resources were formulated and promulgated, urging mining enterprises to do a good job in geological environment protection and restoration and management in accordance with the principles of "whoever destroys it will govern it" and "whoever governs it will be responsible". Over the past few years, more than 80 million yuan has been invested to treat 19 subsidence area and 96 waste rock piles. More than 0.5 million mu of tailings pond/kloc-0 is reclaimed every year, and the land reclamation rate reaches 46.3%. 88% of mining enterprises adopt underground filling method of mineral processing tailings, reducing tailings discharge by 2 million tons every year; Three companies use gold tailings and granite sawdust to refine building materials. In 2003, the municipal government invested 26 million yuan to transform a gold tailings pond covering an area of about 300 mu in the central area of the Development Zone into a Phoenix Ridge Park integrating leisure and entertainment, which became an important landscape for urban greening. In terms of sustainable development of resources, we will vigorously implement the strategy of "prospering industry with gold". In the upstream, further intensify exploration, implement the "going out" strategy, and do a good job in strategic reserve and strategic expansion of resources; In the middle reaches, give full play to the advantages of resources and funds, guide gold enterprises to develop and apply projects in auto parts, electronics, medicine and other fields other than gold, and gradually realize the semi-underground and semi-above-ground industrial pattern of gold enterprises; In the downstream, with the construction of gold and jewelry market as the starting point, we should pay close attention to gold, silver, copper, sulfur, iron, arsenic and other elements to lengthen the industrial chain. We are preparing to build a gold science and technology R&D center, increase the recruitment and introduction of gold professionals, and increase the development of R&D to the middle and lower reaches of gold industry.

(2) Establish a new production concept and promote the transformation of economic growth mode with circular economy.

According to the principles of reduction, reuse and recycling, we will reduce the dependence of economic development on resources and improve the quality of economic growth. First, adjust the industrial structure according to the concept of circular economy. Rationally adjust the city's industrial layout and product structure, limit and eliminate backward processes, technologies, equipment and products that waste resources and pollute the environment, close enterprises and production lines that seriously waste resources and pollute the environment, and build a green industrial system that meets the requirements of circular economy. In 2004, 22 enterprises without pollution control facilities were closed according to law, 47 small chemical enterprises were cleaned up, and some enterprises with poor management of pollution control facilities and substandard wastewater discharge were suspended for rectification. The second is to speed up technological innovation and tap the potential of comprehensive utilization of resources. For the resource utilization enterprises in the city, we should guide them to improve the comprehensive recovery ability of resources and improve the utilization rate of resources, so as to expand the economic benefits of enterprises. In 2004, the city's gold enterprises recovered more than 500,000 tons of scrap and waste low-grade ore, and recovered more than 200 kilograms of gold, worth more than 20 million yuan; * * * treated 4.75 million tons of solid waste, and the comprehensive utilization output value was 765.438 billion yuan, an increase of 56%. The comprehensive utilization project of polymetallic associated gold and silver ore with an investment of 654.38+0.35 billion yuan in Jinchiling Gold Mine won the first prize of provincial science and technology while improving the oxidation recovery rate of complex gold and silver concentrate and recovering valuable metals such as lead, copper and zinc from tailings. After it was put into production in August 2004, the daily processing capacity of complex gold and silver concentrate was 100 tons, and the recovery rate of gold and silver increased from 50% to over 97%. After the project test is successful, we will promote it in time. At present, three gold smelting enterprises in this city have adopted this technology. With this technology, the gold industry of China Central Mine can process 230,000 tons of ore annually, with an economic benefit of165438+500,000 yuan. The multi-element extraction project of complex gold-bearing minerals in Guo Da Gold Co., Ltd. added 65,438+10,000 tons of complex gold-bearing materials, increased 4,845 kilograms of gold and 6,953 kilograms of silver, created economic benefits of 27 million yuan, and won the second prize of national technological progress. The third is to promote energy conservation and consumption reduction and improve the utilization level of energy and raw materials. Strengthen the management of energy, raw materials and water consumption in key industries such as gold, auto parts, electronics and chemical industry, and adopt technologies, processes and equipment with high efficiency, low consumption and low pollution to improve the output efficiency of energy and raw materials. Nine enterprises with annual energy consumption of more than 5,000 tons, such as Jinbao Electronics, Yingezhuang Gold Mine and Thermal Power Plant, were monitored, and energy-saving rectification suggestions were put forward 123, with a rectification rate of 87% and an annual energy-saving potential of 6,800 tons. In 2004, these enterprises consumed 0.72 tons of standard coal per 10,000 yuan of output value, achieving a comprehensive energy saving rate of 4.3% and energy saving and efficiency improvement of 28.6 million yuan. Linglong Rubber Co., Ltd. invested 3.695 million yuan to install 9/kloc-0 sets of equipment, which improved the water reuse rate from 73% to 96.4%. Jinbao Electronics invested 2.2 million yuan to build a new copper foil rinsing water recovery and purification project with an annual treatment capacity of 100 tons, with an annual recovery of electrolytic copper 120 tons, 800,000 square meters of softened water and a profit of more than 3 million yuan. The fourth is to promote cleaner production and strengthen pollution control. On the one hand, pollution control in key areas has intensified. In view of the fact that there are many fan enterprises in our city, which are widely distributed and the sewage treatment is not thorough, a special rectification of fan production has been carried out. Since last year, 43 enterprises have built new pollution control facilities with a daily wastewater treatment capacity of 6,450 tons. At present, the pollution control rate of fan enterprises in the city has reached 100%. Pay close attention to the pollution control of chemical wastewater and carry out centralized rectification of 20 enterprises with problems within a time limit; On the other hand, guiding enterprises to carry out cleaner production has realized the transformation from terminal treatment to pollution prevention. In 2003, Xiadian Gold Mine took the lead in passing the ISO 14000 environmental management system certification in our city. At present, nine enterprises in this city have passed ISO 14000 environmental management system certification, and six enterprises are conducting cleaner production audit.

(3) Establish a new environmental concept and promote the establishment of an eco-city with circular economy.

Eco-city is an important model of regional development cycle, which embodies the value orientation of urban and rural residents. To this end, we firmly establish the people-oriented environmental concept, incorporate the creation of eco-city into the overall planning of circular economy, make overall consideration, and promote it simultaneously so that urban and rural residents can produce and live healthily in a good environment. The first is to build a "green capital". Focusing on improving the urban and rural ecological environment and improving the ecological carrying capacity of the city, a large-scale greening project focusing on the greening of the east and west exits of the city, the management of barren hills, the transformation of wasteland and the greening of "every village" roads was implemented. In 2004, the city's green area was 6.5438+0.85 million mu, including 2,500 mu of barren hills and 2,000 mu of tidal flats, and nearly 400 kilometers of expressways and "every village" roads in Wei Wu were afforested. Nearly 200 thousand people in the city participated in voluntary tree planting activities and planted more than 500 thousand trees; The newly rebuilt green area in the urban area is 600,000 square meters, and the east and west exits of the urban area and 1 1 main roads are afforested to a high standard. Up to now, the city's forest coverage rate has reached 33.2%, the urban green coverage rate and green space rate have reached 36. 1% and 32% respectively, and the per capita green space area has reached 16.3 square meters. The second is to build a "green city". Starting with improving the function and taste of the city, we will optimize the production and living environment of the city. First of all, urban planning has been adjusted and improved. According to the requirements of circular economy, the city scale, functional area layout and infrastructure construction should be rationally planned, and the connection between urban industrial systems and the size of environmental capacity should be fully considered. In 2004, we hired relevant experts to revise and improve the overall urban planning, highlighting the two major urban landscapes with Wenquan Road and Chengdong River as the "golden axis and silver line", forming the urban functional zoning of "one city and six districts", fully demonstrating the new image of a city with sky blue, clear water and green veins. Second, increased investment in urban environmental protection. In recent years, a total of 600 million yuan has been invested to build urban water supply and drainage facilities, sewage treatment, garbage transfer stations, central heating and gas supply and other environmental protection infrastructure. At present, the total area of urban heating has reached 6.5438+0.62 million square meters; The annual water supply in urban areas reaches 6.5438+0.2 million tons, and the per capita domestic water consumption is 90 liters/day; The garbage harmless treatment rate and cleaning rate reached 100%, and the sewage treatment rate reached more than 73%. In 2003, we invested more than 98 million yuan to develop urban central heating and dismantled more than 50 boilers. The third is to start the comprehensive management of urban transit rivers. Since last year, we have invested 70 million yuan to comprehensively start the comprehensive transformation of the two transit rivers, namely Chengdong River and Luoshan River, and comprehensively improve the river water storage, flood control and pollution interception, greening, lighting, and buildings along the river. After completion, it will become a beautiful waterfront sightseeing belt in our city. Fourth, urban environmental monitoring has been comprehensively strengthened. Focusing on improving urban environmental quality, we will pay close attention to air pollution control and the construction of smoke and dust control areas and environmental noise standard areas. At present, the overall environmental quality of the city has improved steadily, and the national second-class standard has always been maintained. The water quality of centralized drinking water source, urban surface water and drinking water source all reached 100%, the coverage rate of tobacco control area reached 100%, and the coverage rate of urban noise reached 78.76%. The third is to advocate "green consumption". Establish a green consumption system with the government as the leading factor and society as the main body, and vigorously promote green procurement and social sustainable consumption. At the government level, we have established a green procurement system, giving priority to purchasing energy-saving, water-saving and recyclable products. At the same time, give priority to the use of energy-saving and water-saving products for new projects and new urban public facilities; At the social level, vigorously carry out activities such as "green lighting", national water saving, green community and building energy-saving demonstration community. In 2004, the city's completed construction area was 860,000 square meters, the application of new wall building materials reached 98%, and Jindu Garden Community basically reached the standard of building energy-saving demonstration community. The fourth is to develop "green agriculture". In the field of planting, we will vigorously promote agricultural standardization and industrialized production, and accelerate the development and construction of pollution-free agricultural products and bases. In recent years, five enterprises, such as Qiangliyuan Soymilk, Jinhai Juice and Jincheng Noodles, have obtained the national green food certification, and the city's green food base has reached 80,000 mu, and the pollution-free food base has reached 250,000 mu. In the field of aquaculture, focusing on the comprehensive utilization of farm sewage, we will actively promote new technologies for biogas production and realize a virtuous cycle of breeding. Up to now, the city has built 6000 cubic meters of biogas digesters, which not only controls pollution, but also increases farmers' income by 500 thousand yuan every year; In the field of agricultural products processing, a recycling system has been established to put the waste generated in the processing back to work and produce feed and fertilizer. At present, fruit juice processing enterprises such as Jinhai, Jinchao and Lianlei in our city produce more than 8,000 tons of pomace every year, all of which are recycled to produce feed, which can increase the benefits by more than 3.2 million yuan every year.

Thirdly, the role of Zhaoyuan municipal government in promoting circular economy.

Zhaoyuan Municipal Government has fully played a leading role in the process of promoting circular economy, taking planning as the premise, policies as the guarantee and publicity and education as the means, forming a joint force to vigorously promote circular economy in the whole society. Mainly reflected in the following four aspects:

(1) Strengthen planning guidance. On the basis of a comprehensive study of the strategic planning of circular economy, the Opinions of Zhaoyuan City on Vigorously Developing Circular Economy and Building a Resource-saving Society was formulated, and the objectives and tasks of building a resource-saving society by stages were put forward, and the basic approaches and key areas were defined. At the same time, we should bring the development of circular economy into the 11th Five-Year Plan, change our ideas and take promoting comprehensive, coordinated and sustainable development as an important goal throughout. The city has also set up a leading group with the mayor as the team leader, the mayor in charge as the deputy team leader, and the main leaders of 24 departments including the Municipal Environmental Protection Bureau, the Development Planning Bureau, the Economic and Trade Bureau, and the Finance Bureau as members, to determine the working organization and division of responsibilities, so as to be responsible at all levels and implement them step by step; Study and formulate the promotion plan and implementation plan for the development of circular economy, strengthen cooperation among departments and establish an effective coordination mechanism.

(2) Implement policy guidance. While earnestly implementing national and provincial preferential policies such as tax reduction and exemption to encourage the development of circular economy, we will further improve the construction of local industries, finance and taxation, investment and incentive mechanisms, and vigorously support the construction of circular economy projects. In the direction of industrial development, give priority to the development of circular economy and encourage the development of industries such as resource conservation, comprehensive utilization of resources, clean production and waste reduction; In terms of funds, actively guide financial and credit institutions to support circular economy projects and encourage social funds to invest in circular economy; In terms of policy, the municipal finance has established a special fund for resource conservation at the municipal level, and arranged 2 million yuan each year to support and reward the development of circular economy. In 2004, we selected eight enterprises in gold, auto parts, electronics, chemicals, textiles, food and other industries for pilot and key support. At the same time, the preferential policies for enterprises in resource conservation and comprehensive utilization were fully implemented, and the value-added tax was reduced or exempted by 7.58 million yuan throughout the year.

(3) Implement key promotion. Always put the development of circular economy in an important position, strengthen safeguard measures and make efforts to promote it. The first is to strengthen the assessment. We have adjusted and improved the assessment methods of economic work at the township level, intensified the assessment of developing circular economy, and mobilized the enthusiasm of various departments and enterprises at all levels; The second is to intensify inspections. Improve and strengthen the environmental monitoring team, strengthen the inspection density and investigation of environmental damage and waste of resources, and improve the rigidity and seriousness of environmental law enforcement; The third is to implement rational investment promotion. On the one hand, circular economy projects will be included in the city's investment promotion project library, and dynamic management will be implemented, focusing on external promotion and attracting foreign investment; On the other hand, a project benefit evaluation office has been set up to evaluate the benefits of new projects according to the requirements of circular economy, and to restrict the introduction of projects with high energy consumption, high emissions and low benefits.

(4) Improve public participation. Give full play to the role of news, radio, culture and other departments and social organizations, vigorously publicize the laws, regulations, principles and policies for developing circular economy and saving resources, carry forward advanced models, publicly expose the phenomenon of resource waste, and form a good atmosphere for saving resources, rationally utilizing resources, preventing pollution and protecting land in the whole society. Strengthen publicity and education at all levels of society, guide enterprises and society to change their concepts, establish a sense of responsibility for sustainable consumption, resource conservation and environmental protection, improve the awareness and participation of the whole society, and make developing circular economy and building a resource-saving society become the conscious behavior of the public.

Some enlightenment of developing circular economy in Zhaoyuan city.

Zhaoyuan City has made some useful explorations in developing circular economy and building a resource-saving society, and achieved tangible results. In practice, I got some experience and inspiration. There are mainly the following three aspects:

First of all, government promotion is an important foundation for developing circular economy. Developing circular economy is a complex system engineering, involving all walks of life, industries and fields. In practice, we must persist in taking the government as the leading factor and system innovation as the guarantee, so as to achieve unified planning, step by step implementation and step by step. In the process of guiding the development of circular economy, the government takes certain economic support and policy encouragement, as well as necessary administrative intervention measures, which are indispensable and important conditions for promoting and developing circular economy.

Secondly, market-oriented operation is an important way to develop circular economy. To develop circular economy under the condition of market economy, we must respect objective laws. In the early stage of the development of circular economy, it is very important for the government to give full play to the role of financial leverage and industrial orientation, and to establish a market operation mode of "government guidance, enterprise investment and social participation", which is also conducive to the formation of a joint force of the whole society to promote circular economy. With the in-depth development of circular economy, the government should gradually shift from investment guidance to preferential policies, change investment attraction into market choice, and gradually cultivate and improve the spontaneous and efficient operation mechanism.

Third, scientific and technological innovation is an important guarantee for developing circular economy. From a technical point of view, the main problems facing the development of circular economy are high energy consumption, high emission and low utilization rate. To solve these problems, fundamentally improve the efficiency of resource utilization, reduce energy consumption and emissions, and promote the recycling of resources, we must combine local conditions, rely on scientific and technological innovation, continuously introduce, develop and apply advanced technologies, processes and equipment, and establish a technical support system for circular economy in line with local characteristics.
